The organizers would like to invite the submission of = abstracts for several talk openings in the following symposium.

"Docking and Scoring: What have we learned and where are we now?"<= /b>

Ses= sion 1 (half day): Learnings from docking & scoring evaluations with a pharmaceutically relevant data set
For the past five years, docking & scoring program developers and application scientists have been invited to the GlaxoSmithKline (GSK) Collegeville, PA site to evaluate their software on GSK proprietary data se= ts. During this session some of those who took up the offer will share th= eir insights from running evaluations on these sets without knowing the conform= ations or affinities of compounds ahead of time. They will share learnings towards improving their docking & scoring software.

Session 2 (half day): Computational Approaches for Fragment Screenin= g
The chairs of the session are seeking abstract submissions in the area of computational approaches for fragment screening. We are especially interested in fragment pose predictions with RMSD or other applicable metri= c computed for docked fragments (where the molecular weights of the fragments= are <250 Daltons). Additionally, presentations will be considered whic= h focus on enrichment - ROC or BEDROC values should be included if appropriat= e. Analysis centering on diversity of actives retrieved (i.e. scaffold hopping) is of interest.

Ses= sion 3 (full day): A Review of Docking Programs
A 2004 symposium at the Philadelphia ACS meeting featured a day of overview presentations by the developers of a large number of docking algorithms. In an effort to find out what has changed in the last six years we ar= e organizing a day long review of docking programs. Instead of an overv= iew we are requesting that algorithm developers spend 15 minutes describing the= new features in and improvements to their algorithms over the last six years. The last 10 minutes of the presentation will focus on algorithm performance for two tasks against public data sets. The first task wi= ll be binding mode prediction against the 85 structures in the Astex data set. The second task will be virtual screening performance against the DUD data set. There will be two speaking slots that are open for abstract submission. The remaining speaking slots will be by invitation.

There are 2 to 3 speaking slots in Session 2 and two speaking slots in sess= ion 3. The abstract submission deadline is March 30.
